Rahu
Effects of Rahu in the 8th House
Analysis based on traditional Jyotish texts. Full citations at the end of this page.
Quick answer: Rahu in the 8th house (Randhra Bhava, longevity and hidden resources) points to compromised longevity, a pattern of rising to real honor and then falling from it, and a conduct profile the classical sources call despicable in plain language. The texts make no attempt to soften any of it.
What Rahu in the 8th House Means for Longevity and Health
The 8th house, Ashtama Bhava or Randhra ("the hole" or cavity), governs longevity, hidden resources, and the manner of one's exit from the world (Phaladeepika 8.34). Rahu's essential nature is Tamo, darkness, a designation fixed across the tradition and stated explicitly in the Chamatkara Chintaamani (Sloka 1 and 8). Darkness sitting in the hidden house obscures clarity in health, wealth, and reputation alike. The Phaladeepika is direct on the physical picture. It names Alpayu, a shortened or compromised term of life, alongside Udara-roga, marked susceptibility to belly and abdominal pain, and a distinct tendency toward gout or rheumatism, pointing to long-term inflammatory or circulatory trouble. Underneath all of it sits a general depletion of physical resilience.
Rahu in the 8th House: Rise and Fall in Status
The Chamatkara Chintaamani (Sloka 8) describes a specific socio-economic pattern rather than uniform decline: the native is honored by kings and scholars, and then meets Bhramsha, a sudden fall from that elevated position. This is not one bad break. It is a structural rhythm. Three terms sharpen this picture. Shrama-granthi, the "knot of labor," describes effort that stays tangled or blocked, so that gains demand extreme, obstructed toil rather than arriving cleanly. Social isolation follows a similar shape: the native is at risk of being abandoned by people, which compounds into the depletion of accumulated wealth as networks fall away. And Vraghna-shatru, "the Sun's enemy," reflects Rahu's role as the eclipser of the Sun (vitality, authority), which in the house of death sets up both a drain on life force and friction with people in positions of power.
Rahu in the 8th House: Conduct and Legacy
The Phaladeepika does not stop at circumstance. It names a tendency toward Dusta Karma, conduct that deviates from established ethical norms, described plainly as despicable acts. The same passage associates this placement with few children, a real limitation on sustaining a long-term lineage. Underneath both sits a native who is, in the text's words, distressed and hard-working at once, worn down by the Shrama-granthi named above, and generally unsettled: a life short on stability and long on restless searching for security.

Sources
Phaladeepika 8.34 is the primary source for longevity, physical health, conduct, and progeny. Chamatkara Chintaamani (Rahu, Sloka 8) is the primary source for the rise-and-fall pattern, labor, and the Sun's-enemy dynamic. The Brihat Jataka establishes Rahu's general classification as Tamo, which frames its behavior in this house specifically.
